The two ropes may be wrapped 5 tower lift affording a free outlook not hindered around the drum in opposite directions and for 5 by guiding devices for the cage and permitting this purpose the two halves of the drum are proof a general view, by a slow turning movement vided with helical grooves in opposite directions of the cage around the tower axis and if desired to serve as guides for the two ropes as they are also around the axis of the cage itself. Thus wound onto the drum. Thus while one rope is 10 as compared to ordinary lifts a chance will be wound onto the drum the other is unwound. 10 given for enjoying the view by an all around As shown in Fig. 5 the parts are so arranged outlook without need for people to change their as to prevent a twisting together of the two ropes seat in the cage.
